the effect of esp materials on medical studentsreading proficiency

چکیده این تحقیق " مواد درسی " را به عنوان یکی از بحث برانگیزترین موضوعات آموزش زبان تلقی کرده و درتلاش است به سه سوال عمده پاسخ دهد: 1) آیا بکارگیری جزوات گرداوری شده توسط گروهی از مدرسین تاثیر بسزایی در میزان توانش خواندن و درک متون انگلیسی دانشجویان پزشکی دارد؟ 2) آیا استفاده از مواد درسی اصلی( بین المللی )، توانش خواندن و درک متون انگلیسی دانشجویان پزشکی را به طور چشمگیری تحت تاثیر قرار م...

The effects of electropulsing on metallic materials

The influence of electropulsing on metallic materials is reviewed, with a focus on phase transformations and grain refinement. While a large and growing body of literature exists on the topic of electropulsing, the mechanisms governing the process are not currently fully understood. Furthermore, the effects of electropulsing on microstructure and mechanical properties are not yet clearly define...

Small Punch Testing of Artificially Aged Gamma-Sterilized Polycarbonate Urethane Acetabular Components

INTRODUCTION: Polycarbonate urethane (PCU) has been investigated as a candidate bearing material for total acetabular replacement and unicondylar knee replacement [1-4], and is currently being used in a pliable acetabular component (AIC Acetabular Buffer: Active Implants Corp., Memphis, TN). However, the susceptibility of PCU to post-irradiation aging is not yet fully understood. Furthermore, d...
